Thanks a lot, José, for your reply.
You might suggest that to MAXON.

The Cloth based effect of tearing is not producing new Geometry, as in parts torn apart, for that the Cloth Objects needs to be added, otherwise: Polygons along the “split” will grow larger. So, I guess it needs more attention than just applying a vector to a given point. But I’m confident that there is a solution, but it needs some more people to point to that need, so developing time is assigned to this.
I saw the X-Particles tear effect in a preview, but I have not worked with it nor to see if there is maybe a better solution, given Alembic export as target. It seems to work differently, and duplicate edges, which should give a point velocity data, if available.
My best wishes
